The DBH 8783 radial shaft seal is a lip seal mounted in a component housing that seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its designation 8783 corresponds to a size of 20.00 mm shaft diameter, 37.00 mm housing diameter and 8.00 mm height, with Lx design. It is used in pumps, electric motors, gearboxes and power transmission equipment operating with shafts of that diameter.

The 8783 is a single-lip seal with metal case and elastomer, identified by the Lx design. Its dimensions are 20.00 mm shaft diameter (d), 37.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design defines the geometry of the lip and the outer body, so it is advisable to verify that the housing and shaft meet those dimensions before installing it. DBH is a brand that MR carries.

It is used in rotating equipment where two environments must be separated: gearboxes, centrifugal pumps, electric motors, reducers, mixers and transmission shafts. It also appears in applications exposed to dust or splashes, where the seal prevents oil leakage and the entry of contaminants. It is a wear part: when the lip hardens, crystallizes or loses elasticity, lubricant leakage begins to appear.

To select it, compare the shaft diameter, housing diameter and height with those of the original seal. Check the condition of the shaft surface: scratches, wear or burrs damage the new lip. The housing must be clean, free of ridges or remnants of old sealant. During installation, lubricate the lip with the same oil or grease used in the equipment and press evenly, without striking the elastomer. If the shaft has a marked groove, consider a nearby size or a wear sleeve.

If you need a seal equivalent to the 8783 or a nearby size, send us the code, the brand and the shaft, housing and height dimensions. With that data we verify alternatives within the DBH line or other brands we carry. We can also guide you if the Lx design is not the one for your application and a different lip or case type is needed.
